6 Claims.

'I'his invention relates to screens intended for use with windows ofV various types including easements or pivoted sash windows. v

Window screens, as ordinarily made with rigid frames, are expensive to construct; unwieldy incident to application to the windows; liable to distortion and warping and therefore notv dependable always for maintenance of a perfect perimetric seal with the frames of the windows; and, moreover, do not lend themselves toobject the provision of a window screen. which,-

by virtue of having its wire mesh supported. in a frame of flexible non-elastic material, `an be rolled singly or with a number of others, into a compact package; which is light and easily manipulated during application to a window;`

which, on account of its inherent exibility, adapts itself readily to any irregularities of the window frame; and which, on the whole, is conducive to very economic manufacture in quantity.

In connection with a screen havingthe indicated attributes, it is a further object of my invention to provide novel means for securing the screen to the window frame with capacity for ready and quick detachment.

Still other objects and attendant advantages of my invention will be manifest fron@ the following detailed description of the accompanying drawings, wherein Fig. I isan inside elevation of a metallic easement window with ascreen conveniently embodying the present improvements.

Fig. II is a staggered vertical section of the organization taken as indicated by the arrows 1li- II in Fig. I. I

Fig. III is a detail view showing the section of the flexible strip material employed in forming the supporting frame of the screen, and illustrating the manner in which the said material is applied to the edge of the wire mesh.

Fig. IV is a detail sectional view crosswise of an edge of the finished screen.

Fig. V is a fragmentary view of a corner of the screen showing a form of grommet by aid of which the screen is secured to the frame of the easement. r

Fig. VI is a detail sectional view taken as indicated by the arrows VI-VI in Fig. I, featuring more particularly the means whereby the bottom edge of the screen is dctachably secured to the easement frame. V

Figs. VII and VIH are views coresponding to Fig. IV showing alternative forms of construction of my improved screen.

Fig. IX is a fragmentary view of the in sidel of a window showing an alternative embodiment of securing means forthe upper edge ofthe screen; and,

Fig. X is a fragmentary sectional view taken as indicated by the arrows X--X in Fig. JX.

The metallic casement window shown in Figa. I and II for convenience in illustrating my invention is ofconventional construction, its frame 10 being formed with head, sill and jamb rails 11, 12, 13 and 14 of Z cross section. The swinging sash of the` easement indicated at 15 is likewise formed from Z bar stock, and closes against the frame 10 with a double weather seal inl a manner characteristic of such windows. L

'Ihe screen with which the present invention is more especially concerned is generally designated by the numeral 16 in Figs. I and Il, the same comprising a sheet of ilexlble screening 17, in this instance of wire mesh,` anda frame 18 in `which Vthe edges of the wire mesh are embedded, as

shown in Fig. IV. This frame 18 is formed from exible non-elastic strip material which may be of any suitable composition or of suitably vulcanized rubber, with the cross sectional conilgura-l tionshown in Fig. III. Centrally of its width, the strip material has a longitudinal depression 19 which facilitates folding of the strip ,over the edges of the wire mesh 17, after the manner illuslapped margins of the wire mesh 17, by use of a suitable cement. .If rubber is employed as the base .of the composition-the folds of the strip may be permanently united by vulcanization. Adjacent the central depression 19 which denes the line of folding, the flexible strip material is provided with a pair of longitudinally-extending projections or fins 20x, which, in the completed screen, project laterally from one face of the non-rigid frame 18. When the screen 16 is applied to the window, as shown in Fig. 1I, these ns 20 yield- 105 ingly bear against the inner face o f the-window frame 10, thus constituting a perimetric seal against entrance of insects around the screen edges.

As a means for detachably securing the 110.

PATENT OFFICE ,A

16 to the window, I have provided the screen frame at the top and bottom corners with metallic grommets 21 and 22 (Figs. I, II, V and VI) which, in this instance are circular and adapted to engage projections 23 and 24 respectively on the in-side face anges 11a and 12a of the head and sill rails 11 and 12 of the window frame 10. The upper pair of projections 23, it will be observed from Fig. II, are in the form of screw studs with spherical heads 25 behind which circular springs 26 lodged in internal circumferential recesses of the grommets 21 engage with a snap t as the screen 16 is applied. The projections 24 at the bottom of the window are likewise in the form of screw studs, but with plain shanks 27 to the ends of which, keeper pieces 28 are pivotally attached. Normally, the keeper pieces 28 occupy the crosswise position illustrated in full lines in Fig. VI; but by virtue of their pivotal attachment, they may be swung into alignment with the stud shanks 27, as shown in dot-and-dash lines, so that the grommets 22 may be slipped on and off incident to application and removal of the screen 16. The devices 24 thus permit quick detachment of the bottom edge of the screen 16, this being particularly advantageous in connection with a casement window, such as herein shown, in that it affords ready access to the sash 15 for the purposes of opening and closing it, aswell as cleaning it.

Fig. VII shows an alternative construction of my improved screen in which the upper edge of the screen frame 18b is reinforced by a strip 30 of metal. This metallic strip 30 may be soldered or welded to the wire mesh 17h; and incident to application of the exible frame material to such mesh, incorporated in the fold of the said material as illustrated. A construction similar to the above may, of course, be resorted to at the other edges of the screen.

In Fig. VIII, the wire mesh 17e is rolled about a reinforcing rod 31, likewise of metal, which rod is enveloped within the fold of the flexible material of the screen frame 16e in precisely the same manner as described in ,connection with the reinforcing strip 30 of Fig. VII.

In lieu of the screen attaching means featured in Figs. I, II, IV. and V, I-may employ the alternative type shown in Figs. IX and X, wherein the grommets 21d for the top edge of the screen 16d are horizontally elongate, and adapted to engage with hook-like projections of brackets 23d fashioned from sheet metal and secured fast to the top rail 11d of the window frame 10d. The modified securing means just described is obviously equally as efficient, from the standpoint of permitting quick and ready attachment and detachment of the screen 16d from the window, as the form illustrated in Figs. I, II, V and VI.

' The foregoing alternatives are all to be considered typical of other variations possible within the scope of the appended claims, both as regards the construction of the screen and the means for detachably securing it to the window. While I have herein specifically shown and described my improved screen in association with a casement window, it is evident that it may be employed with equal advantages in connection with other kinds of windows. It is furthermore to be understood that I do not wish to limit myself to the use, in the construction of the screen, of the materials specifically mentioned, since, for example, a transparent membrane of celluloid or the like may be substituted in place of the wire mesh and the screen employed after the manner of a storm sash in winter.

Having thus described my invention, I claim:

l. In a Window screen comprising a sheet of wire mesh, a supporting frame therefor of retroverted flexible elastic strip material in which the perimetric edges of the Wire mesh are securely embedded.

2. In a window screen comprising a sheet of flexible reticulate material, a supporting frame therefor of medially overfolded flexible elastic composition strip material unitedly-engaging the surrounding edge of the reticulate material, said strip material having a longitudinal n to yieldingly engage the window frame and form a perimetric seal therewith.

3. In a window screen comprising a sheet of flexible reticulate material, a supporting frame therefor of medially overfolded flexible elastic composition strip material unitedly-engaging the surrounding edge of the reticulate sheet, said 110 strip material having a longitudinal depression in one of its faces to facilitate folding and a longitudinal fin along one side of the depression adapted to yieldingly engage the frame of the window and form a perimetric seal therewith.

4. In a window screen comprising a sheet ofv flexible screening material with a perimetric edge reinforcement, a supporting frame therefor of flexible over-folded elastic material in which the reinforced surrounding edge oi' the screen body is securely embedded.
